Just prepar your self

If you miss the rapture, remember today try not to panic, realize you missed the rapture and you are now in 7 years of tribulation. Get a bible and pray, do your best to find some survival equpiment, and have a survival plan. you need water it all be contaminated, you will need food, there won't be any and without the mark of the beast you want be able to buy try to find shelter in a cave if you have to. Make no alliances with the antichrist nor the false prophets.

Do not take the mark of the beast. (Matthew 7:15) "Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. (Matthew 24:5) For many will come in my name, saying, 'I am the Christ,' and they will lead many astray. (Revelation 13:16-17) Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name.
